Oh, yea... You CAN buy ammo from Lazzeroni. ...For $130+ per box.
Did you even read my post?
If you aren't paying $5,500+ for a Lazzeroni rifle, then it isn't a Lazzeroni.
If it doesn't come from Lazzeroni, then it's a knock-off. The PTG "Lazzeroni" reamers are not licensed. They're reverse-engineered 'copies'. And, like PTG reamers for .458 SOCOM and several other cartridges, they're 'copies' that have some rather nasty mistakes that can create dangerous situations for anyone that chambers a rifle with those reamers.
If yours works, then more power to you. Give the lottery a shot.
You like the cartridge. We get it. Will you let the original poster have a discussion about the Nosler cartridges, already?
And your "custom" rifle may or may not be worth the cost, depending upon what day of the week the 'smith decided to get black-out drunk and come in hungover. There is a 'World Class' gunsmith 2 miles from me, well renowned for his work with the 550 RNS Magnum and the dozens of his rifles that have been in gun magazines, built either for dangerous game in Africa, or for competition shooters in the states.
I asked him to open an ejection port, and provided a
dimensioned drawing specifying exactly what I wanted; along with cutting and crowning a barrel, and drilling and tapping for the new front sight position.
He cut the port free-hand and completely screwed the pooch, by cutting not just the wrong shape, but notably oversized.
Then he cut the barrel to the wrong length, drilled the sight base screw holes the wrong diameter, and used the wrong type of crown.
Oh, but wait, there's more! He also stripped the bluing off of the whole rifle and reblued it to get
his preferred color, even though I specifically instructed him not to touch the finish (other than the damage done by opening the port and working on the barrel). And then he tried holding the rifle for ransom (and placing a mechanics' lien on it, through the Sheriff) when I refused to pay for the WRONG work and UNAUTHORIZED work for which he was charging me.
Quality!
Regardless of whether or not you can trust any given gunsmith... you're missing one very important point. Nosler
guarantees the performance of their rifles. They're not Tikkas, or Marlins, or Remingtons, or Savages, that just get slapped together, thrown in a cardboard box with a loose trigger lock that will beat the crap out of the rifle, and shipped out by the pallet. They're tested, individually, before being certified and carefully packed for individual shipment.
